This accessibility feature on Apple’s mobile operating system allows users to employ their iPhone, iPad, or iPod touch as a remote microphone, sending audio to compatible Made for iPhone (MFi) hearing aids or AirPods. For instance, an individual in a noisy environment might place their iPhone near a speaker and listen to the amplified audio through their AirPods, effectively isolating the desired sound.
The primary benefit is enhanced auditory awareness and improved communication in challenging listening situations. Historically, this function evolved from assistive listening technologies aimed at aiding individuals with hearing impairments. It also offers discreet monitoring capabilities, serving as a supplementary tool for caregivers or parents wanting to remotely hear sounds in another location.
